Title: Mos type semiconductor device
Inventor: KOTANI KIYOUHIKO
IPC: H01L29/417
Filed: 1978-12-06
Abstract: PURPOSE: To improve gate voltage-drain current characteristics, by using a gate shape whose channel length is varied by channel width direction.  
     CONSTITUTION: An n-type drain 2 and an n-type source 3 are formed on a p-type Si substrate. A gate 5's length is rectilinearly shortened in the direction of width perpendicularly to a channel length l. And therefore, when the channel length l becomes short, the threshold value voltage goes down, and short channel effect starts appearing from a certain point. Now, the gate 5 is formed in such a manner as to give rise to the short channel effect at the minimum value of the channel length. At this time, if the gate voltage VO is sufficiently high and an entire region of the gate 5 is in a condition of ON, a drain current ID passes the entire area but becomes OFF with descent of the voltage VO and control of low amplification becomes very easy. The shape of this characteristic curve can be finely changed by shape of the gate.

IPC: B23K26/066
Filed: 1997-06-11
Abstract: PROBLEM TO BE SOLVED: To prevent a mask from rising or getting out of position in laser processing by a method wherein moisture or electric charge is supplied onto the surface of the insulating resin layer of a printed wiring board so as to bring a mask into close contact with the insulating resin layer, a laser beam is made to irradiate the insulating resin layer in spots only through through-holes provided to the mask to bore holes in the insulating resin layer. SOLUTION: Moisture is supplied onto the surface of the insulating resin layer 3 of a printed wiring board, and then a mask 4 with through-holes 4a is brought into close contact with the insulating resin layer 3. Or, the insulating resin layer 3 of the printed wiring board is charged with static electricity, and the mask 4 is brought into close contact with the insulating resin layer 3 taking advantage of an electrostatic force. Then, a laser beam is made to irradiate the insulating resin layer 3 through the through-holes 4a to make blind holes 5 in the insulating resin layer 3. Then, the printed wiring board subjected to laser processing is subjected to copper plating for the formation of a copper plating layer 6. Required blind vias 7 are formed, and thus a multilayer printed wiring board 8 with the blind vias 7 is obtained.  By this setup, a mask can be prevented from rising up or getting out of position in laser processing, and the time required for laser processing can be shortened.

Title: Illumination structure
Inventor: SHINOHARA HIDEYA
IPC: G02F1/1335
Filed: 1994-07-05
Abstract: PURPOSE:To increase illuminating efficiency, reduce power consumption, downsize a light source, and reduce a heat radiating structure by constituting a light reflecting part by extending a shielding plate to the front of the light source, and letting light from the light source reflected to a light conductive body by the light reflecting part. CONSTITUTION:An action of a light reflecting plate to conduct light from a lamp 15 to a light conductive plate 10 by reflecting it, is provided by an extendedly arranged part 13 extendedly arranged in front of the lamp 15 by extending a shielding plate 16. A hole 17 to pass light reflected by a light reflecting part 12 of a plate 10 is formed in a position opposed to a display part 19 of the plate 16. In this way, since the plate 16 is used as the light reflecting plate at the same time by extendedly arranging it up to the vicinity of the lamp 15, illuminating efficiency can be improved without increasing the number of constitutive part items. Since generating heat by the lamp 15 can be radiated by the plate 16, adverse influence by the heat generated from the lamp 15 can be prevented. Therefore, since sufficient illumination becomes possible by a light source of comparatively small electric power consumption, the electric power consumption can be reduced, and the light source can be downsized, and a heat radiating structure can be reduced.

Filed: 1990-06-12
Abstract: PURPOSE: To strengthen precleaning discharge action, for intensifying the cleaning of an image forming surface by providing an electrostatic discharge and a high-frequency oscillator on the upstream side of a cleaning device. CONSTITUTION: A discharge illuminator 100 is installed at a position along a photoreceptive belt 10, on a side opposite to the cleaning device 90 across the belt 10. An electric charge remaining on the belt 10 is discharged by the illumination of the discharge illuminator 100. But in this illumination, the charge is not completely eliminated, so that a piezoelectric transducer 104 is installed in the position near the illuminator 100, in a close contact state with the rear of the belt 10. The transducer 104 is selected so as to impart an amplitude by vibration of 1-10μ at an oscillation frequency of about 50-200kHz, so that toner grains are released from the surface of the belt 10. Further, prior to non-electrostatic cleaning, a cleaning corona generator 94 for neutralizing the charges of the toner and the surface of the belt 10 is used in combination with the transducer 104.  Thus, the charges or the toner grains can be more completely neutralized.

Filed: 1997-06-11
Abstract: PROBLEM TO BE SOLVED: To eliminate the lowering of fitting strength and the influence of corrosion by adding stress pressing back a rear surface expanding part opposite to a groove-like recessed part at the outer peripheral of a fixing pin so as to form an expansion press- back part at the groove-like recessed part. SOLUTION: The diameter of the fixing pin 3 is made smaller than the inner piece through hole of an inner piece 2 to allow the inner piece 2 to freely rotate. The groove- like recessed part 31 making a position nearly similar to the side face of the inner piece 2 a start point is provided at the pin 3 projecting from the inner piece 2 and a fitting interference is provided at the inner diameter of an outer piece blind hole 11 to fit the pin 3 to the hole 11 to generate the rear surface expanding part 13 without the expansion press-back part 14 made by plastic deformation caused by the fitting interference at the rear surface of the outer piece 12. Pressing force is added to a part opposite to the groove-like recessed part 31 at the expansion part of the rear surface 13 to form the part 14.  As the result of it, a blind hole inner periphery engaging part 15 is formed at the part 31 to engage the part 15 to the part 31. As pull-out stress is given in the axial direction of the pin 3 and fitting strength is evaluated by measuring force by which a fitting state is broken, as a fixing pin pull-out force, breakage is prevented in spite of the errosion of the fitting part.
